morning right here on this week. Now to a question we've been asking about air travel for some time. Do the electronic dwases really affect the cockpit? You'll remember alec baldwin playing his game and the airline wasn't laughing. A big change could be coming. Please shut off and stow all electronic devices. Reporter: One poll says a third of us forget to and some have refused to. Actor alec baldwin didn't' stop playing "words with friends" and was removed from a flight. But could that change? Are oush our devices safe? Sources tell abc news today, an advisory panel is expected to recommend loosening those rules -- a bit. We went to find out why experts think changes can be made. That's why boeing is using this quiet room, sealed up so that they can listen to your devices to see if they are interfering with the aircraft. I brought in all my devices, phones, air cards, ipad. You can see when it tries to get to the cell tower it really spikes. The cell signal broke through what's considered a safe limit but -- there are a lot of different scenarios, but the bottom line is we're trying to avoid that interference that can cause any kind of degradation of the safe flying of the airplane. Reporter: Which is why plane makers are adding shielding. Some planes are already certified to allow certain electronic devices. How might the rules change? E-readers and some video games could be allowed, or, possibly devices in airplane safe mode, but no cell phone use for calls or data. So what will we be able to use and when will we be able to use it? The faa may not make a decision until september.
